Pericervical Analgesia Versus Analesia With Nitrous Oxide (N2O) in Outpatien Operative Hysteroscopy With Miniresector

May 8, 2024 updated by: Bianca Masturzo, Ospedale degli Infermi di Biella

Comparison of Efficacy Between Nitrous Oxide (n2o) Analgesia and Pericervical Analgesia in Outpatient Operative Hysteroscopy With Miniresector: a Randomized Clinical Pilot Study

This research will have the aim of evaluating and comparing the effectiveness of two methods (analgesia with nitrous oxide and pericervical analgesia, excluding the use of paracervical block due to the increased risk of complications reported in the literature in the control of pain caused during Outpatient Operative Hysteroscopy maneuvers with Miniresector.

Study Overview

Detailed Description

Pain is the primary cause of hysteroscopy failure. It can be attributed to multiple causes, such as manipulation of the cervical canal , uterine distention due to the liquid distension media used during the procedure , operating procedures on the endometrium (as a possible cause of uterine contraction) , until the release of prostaglandins following manipulation of the cervix and uterine distension.

There are few studies in the literature that have compared the various methods of pain control during the hysteroscopic examination. Among these, Ahmad et al., for example, compared the use of the paracervical block and inhalation anesthesia during hysteroscopy: although both proved to be effective in controlling pain, the paracervical block was associated with a greater number of complications. More recently, Solano et al. they defined how the administration of nitrous oxide was equally effective (but with many more advantages) to the paracervical block with 1% lidocaine in controlling pain during hysteroscopy performed using the Bettocchi hysteroscope.

However, for the purposes of this research it is important to take two aspects into consideration:

  • all the studies in the literature that compared the various pain control methods during hysteroscopy were conducted using the Bettocchi Hysteroscope and not the Miniresector;
  • more in detail, there are no studies comparing the use of nitrous oxide and pericervical analgesia during outpatient operative hysteroscopy with miniresector.

Objective This clinical trial will have the aim of evaluating and comparing the effectiveness of two methods (analgesia with nitrous oxide and pericervical analgesia, excluding the use of paracervical block due to the increased risk of complications reported in the literature1) in the control of pain caused during Outpatient Operative Hysteroscopy maneuvers with Miniresector.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention group: pericervical anesthesia

Patients assigned to the Intervention Group will receive Pericervical anesthesia before performing Hysteroscopy.

Specifically, for the administration of pericervical analgesia, Mepivacaine/Lidocaine 1.5% 10/15 ml (max dose 7 mg/kg) will be used and pericervical infiltration will be performed at 0.5 cm depth at 3 and 9 hours.

Other Names:
  • Pericervical Anesthesia
Active Comparator: Control group: nitrous oxide anesthesia
Patients assigned to the Control Group will receive Nitrous Oxide anesthesia before hysteroscopy
Other Names:
  • N2O2 Anesthesia
